SPECIFICATION forming part of Letters Patent No. 422,882, dated March 4,1890.

Application filed November 1, 1889. Serial No. 328,937. (No model.)

To all whom it may concern:

Be it known that I, STILLMAN R. Gnovnn, a citizen of the United States,residing at Attleborough, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement in Buttons, ofwhich the following is a specification.

My invention relates to the improved construction and arrangement of theseveral paras of the button, as hereinafter fully set ort Figure 1represents a back view of the head of the button. Fig. 2 represents asection taken in the line 00 a: of Fig. 1. Fig. 3 represents a sectiontaken in the line y y of Fig. 1. Fig. 4. represents a plan view of thepushers. Fig. 5 is a plan view of the holding-plate of the button-head.Fig. 6 represents a section of the same taken in the line w 00. Fig. 7

represents a plan View of the back-plate of the button head. Fig. 8 is asection taken in the line or a; of Fig. 7. Fig. 9 is a plan view of thespring, and Fig. 10 an edge View of the same. Fig. 11 is an elevation ofthe solid post which is to be secured to the head of the button.

In the accompanying drawings, A represents the head of the button.

B is the back plate, provided with the two recesses a a, the raisedportion a, the central recess 1), and the central perforation c.

O G are the pushers, which are each provided with the semicircularrecess cl, the notch e, and the projecting lip f.

D is the spring, which is made in semicircular form and provided withthe turn ed ends g g, which are adapted to engage with the notches e ofthe pushers O.

The holding-plate E is provided with the backwardly turned wings c' 2',which are adapted to enter the recesses a. a of the plate B, and aresecured therein by any suitable means, and one of the wings '5 isprovided with the inclined stem n, which is adapted to hold the spring Din position.

The rim 7c of the button-head is provided with opposite perforations 8,adapted to re ceive the projecting ends j of the pushers, and the post Fis made solid and provided with a flat head m, and is also made to fitthe perfo ration c at the center of the plate B.

In putting the several parts of the button together the post F is firstpassed through the perforation c in the plate B, so that the flat head mwill be upon the inner side of the said plate, where it will be held bythe faceplate of the button or stone G. The outer ends j of the pushersare then inserted into the perforations in the rim 7c of the buttonhead,the turned ends g g of the spring D placed in proper engagement with thenotches e of the pushers, and the holding-plate E placed in properposition, so that the wingsc' 71 will enter the recesses a a, and theinclined stem n will bear upon the spring D, to hold the same in place.Then by soldering or otherwise securing the wings c' 2' in the recessesa a the several parts of the button will be held in proper workingposit-ion.

The hollow postH of the shoe I is provided with the flange o, as commonin separable buttons, and when the pushers O O are pushed back torelease the post H of the shoe I the rear ends 19 of the pushers, bystriking the inner side of the rim k, will form a stop for 7 5 thebackward movement of said pushers, and the lip f, which also strikes theinner side of the rim is, will form a stop against the outward movementof the same.

I claim as my invention In a button, the combination, with the backplateB, provided with the recesses a a, the raised portion a, the centralrecess b, and the perforation c, of the solid post F, having a flat headm, and held in the perforation c, the perforated rim 7c, the pushers G0, provided with the notch e, for connection with the spring, the lip f,for a stop against outward movement, and the recess cl, the spring D,provided with the turned ends g g, and the go holding-plate E, providedwith the wings c' c', which are secured to the recesses a a of the plateB, and witha projecting stein n, adapted to hold the spring D in itsproper position, substantially as described.
